rawpy/_rawpy.c: No such file or directory about rawpy HOT 15 CLOSED

I just released a new alpha where this issue is fixed. It's based on the latest libraw beta version. Please try with pip install rawpy==0.11.0a1 and comment here if there are still problems.

In your case pip tries to build rawpy from source by downloading the source distribution first (.tar.gz), however rawpy is available as binary distribution (wheel) for Linux, so this should work out of the box without compilation. Please do a pip --version, it may be that your pip is too old. If that's the case, try to install it with pip --use-wheel rawpy (older versions didn't try to install wheels by default).

from rawpy.

I have the same issue in a Debian 9.
The version of pip is 9.0.1 that is the latest and the --use-wheel does not make any difference, but the main question is why it does not compile? I have the libraw-dev installed and i installed it many times with not problems in the past (but not this version).

from rawpy.

@emanuelelaface Are you using a 32bit Linux by any chance? I only supply 64 bit Linux wheels which would explain why pip is trying to install from source. About the fact that it doesn't compile -- this is a bug that's fixed in the next version to be released soon (path issue). You can work-around that by installing cython via pip first to force re-generation of the C wrapper code (without that it would try to compile the bundled pre-generated C wrapper code which is referenced by the wrong path currently).

I am trying it on an ARM64, so maybe it is a problem there. I did some test also with cython but it has the same problem. I will wait the next release.

from rawpy.

Yes, ARM64 would need a different wheel. If you need it working before the next release you can also clone the repository and do a pip install . in the cloned folder. Make sure you have git installed as it's used during building.

Hi @letmaik , I too am facing the same issue attempting to install rawpy to a Raspberry Pi 3 (ARM64). I attempted the pip install . after cloning the repository, but I receive a similar error at
gcc: error: rawpy/_rawpy.cpp: No such file or directory
I've installed libraw from github (pkg-config --libs libraw returns -L/usr/local/lib lraw) and I've tried all solutions given here to no avail :( Looking forward to a hopefully ARM64-compatible future release!

from rawpy.

@thedhruvn Before doing pip install . make sure you have cython installed with pip install cython. Does that work?

from rawpy.

@letmaik , Yes, That did it! Word of warning - I am working with Python3.6 on my Pi, so cython made weird filenames for the .so binaries that led to import errors for >>>import rawpy. I had to go into the site-packages folder within my virtualenv (or go the site-packages within the python installation you have), go to the rawpy/ folder and rename this: _rawpy.cpython-36m-arm-linux-gnueabihf.so to _rawpy.so. Then, after fixing a weird symlink error for my libraw installation and adding it to the shared library path, everything worked. (add a *.conf file [name doesn't matter] with the path to the folder containing libraw.so.16 inside this directory: /etc/ld.so.conf.d/ and then run sudo ldconfig to update your shared path directories).

from rawpy.

@thedhruvn Great that you got it working. The weird filename you saw is normal and also similar on other platforms (e.g. _rawpy.cpython-36m-x86_64-linux-gnu.so on 64 bit Linux), so it's a bit weird that the import failed. The fact that _rawpy.so works is really just a hack but is not how it should be. On your Python that couldn't import the module, can you do pip install wheel and then:

from wheel.pep425tags import get_abbr_impl, get_impl_ver, get_abi_tag, get_platform
print("{0}{1}-{2}-{3}".format(get_abbr_impl(), get_impl_ver(), get_abi_tag(), get_platform()))

That should print cpython-36m-arm-linux-gnueabihf. If not, what does it print?

Hello all,

I am having the same issue as explained in the first post. I am trying to install rawpy on raspbian OS running on raspberry pi model 3. As far as I understood, rawpy install via pip only works for 64-bit OS. Raspbian is 32-bit OS, in this case, is there a way to install rawpy on raspbian ? Thanks.

@letmaik yeap, that solved the issue. thanks.

Hi, I am also trying to install this on a RaspberryPi , I tried pip install rawpy==0.11.0a1 but still get the same error, did you release a fix please :-)

Thanks

from rawpy.

@Levanterman Can you post the exact error? You shouldn't have to use the old rawpy version anymore. If the error is not exactly the same, please open a new issue.

Big thanks for RAWPY :-)
